Influence of Hardening and Tempering Vs. Austempering on Mechanical and Fracture Properties of 65Si7 Steel

Abstract:

The aim of the performed investigations was to determine the influence of two different heat treatment procedures, i. e. hardening and tempering vs. austempering, on some mechanical properties, such as strength, hardness, ductility, contraction, toughness etc., as well as the influence of these procedures on the magnitude of some fracture mechanics parameter for example stress intensity factor K. The experimental investigations were performed on the specimens made of 65Si7 steel (chemical composition: 0.69% C, 1.56% Si and 0.90% Mn).
